Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56666, here are decompositions:
- 3 + 56663 = 56666
- 7 + 56659 = 56666
- 37 + 56629 = 56666
- 67 + 56599 = 56666
- 97 + 56569 = 56666
- 139 + 56527 = 56666
- 157 + 56509 = 56666
- 163 + 56503 = 56666
Showing the first eight; more decompositions exist.
